Answer:
B. Nonmetals
Step-by-step explanation:
Metalloids are elements that have properties that are intermediate between metals and nonmetals, these elements are heat and electricity semiconductors
This means that, generally, metalloids are better conductors of heat and electricity than nonmetals, but not as much as metals.
In the periodic table the metalloids are found diagonally from boron to polonium. The elements that are on the upper right are nonmetals, and those that are on the lower left are metals
